I may have made myself unclear. I am not suggesting that TB revoke the right to have pictures.

I believe, however, that many users -- like myself until this problem came up -- have no idea of how to reduce an overly-large picture. Indeed, they may not even know that it is possible.

I think the evidence of this is the reply that I got from FlyinHawaiian -- that the moderators are aware of the problem.

So what I am suggesting is that TB establish the maximum size permitted (and I don't believe that depends on the screen size -- it would simply have to appear in the space which FTer sees a post without scrolling). Then, if someone tries posting something which is too large he would either (if technically possible) have it rejected or else the mods would remove it and send him a PM with KVS's suggestion.
